"What we need to do is change the way in which people think about guns, especially young people, and make it something that's not cool, that it's not acceptable, it's not hip to carry a gun anymore, in the way in which we’ve changed our attitudes about cigarettes. You know, when I was growing up, people smoked all the time. Both my parents did. But over time, we changed the way that people thought about smoking, so now we have people who cower outside of buildings and kind of smoke in private and don’t want to admit it.” Laughter followed.
